It is possible to tell the difference but I honestly didn't want to go and add in a bunch of technical type icons when the main ones would be pretty much the same.
If people can show me that they arn't 16x9 I'm happy to make its own icon but I thought things like this were a little un user freindly for general public (lower right)http://img41.imageshack.us/img41/83/screenshot035i.jpg

I know 2.35:1 is really different it was an example of the info shown and how it is displayed I just personally think that having a general 16x9 is better and more understandable than 1.85:1 and so on
If someone could get me a common term for the letterbox format I would use that instead of 2.53:1 as well

Jezz, if you are referring to 16:9 vs. 1:85 I might agree. As long as 2:35 is differentiated we could be ok.

On the other hand, just for the sake of discussion, I don't see the advantage of displaying the wrong information. Lots of DVDs report 1.85:1 as aspect ratio and consumers have been exposed to them for years.

Spiff, you might be right (you actually are ) but still I don't think one should create something based on other's mistakes.

I'm the only "simple user" in the discussion here, maybe others will pipe in.

Unless you wanted to convey the three "major" differences in aspect ratio with the icons (numbers apart). You could have a 4:3 icon, a 16:9 icon and a 2.35 icon (I'm referring to the "graphic part"), with different writing in them for 1.33, 1.66, 1.78, etc.
